Costing less than £20,000, it is now possible to collect high quality seabed data, in a simple and cost effective way, with the WASSP WMB160F multi-beam echo sounder.

Better marine mapping

There is now a real alternative to the “high-end” multibeam systems for those wishing to collect useful seabed information.

The WASSP multibeam covers an area of around 4 times the water-depth in a single pass. So a vessel operating in 30 m of water will map a 3D track of the seabed over 100 m wide, in one go, at speeds up to 15 knots.  See demo video.

The WASSP has 112 sonar beams and interfaces with the Olex plotter system for robust and straight-forward operation.
